These are well-constructed, but a little loose, meaning if you have four mouthpieces in the pouch and move around much the cups will hit each other slightly but repeatedly. While that may not bother some players, my lips seem to find and get distracted by even the slightest scratches or dents. I found a different brand that fits tightly.

Holds four mouthpieces securely. In fact, it's almost too good. The pouch is very deep, and it is somewhat difficult to get a cornet mouthpiece out. I ended up buying four saxophone mouthpiece guards to use as plastic "inserts" to give a little more access.
